To 'all whom t may concern.' Y Be 1t known that I, EDWARD T. RANDALL,

a citizen of the United States, and aresident'y of Los Angeles, in thecounty of Los Angeles andState of California, have invented certain newand useful Improvements in Exercising Apparatus, of Vwhich the followingis a specication.

My invention relates to and has for its purposey the provision of anexercising ap paratus of simple, inexpensice and durable construction bywhich various movements of the arms, legs and body can be effected,

i the apparatus including a seat lslidable to.

allow the operator to perform exercises similar to those of rowing, andmeans for locking theseat against movement on the apparatus and in anyadjusted position to permit the execution of other forms of exercises. i

It is also a purpose ofmy invention to provide an exercising apparatusin which the conventional form of lVhitley exerciser` can be employed,or exercisers ofthe coil sprixg type, the-invention being constructed toa low the use of either form of exerciser and to the accoodation ofpersons of various physical dimensions.

l will described only one form of exercising apparatus embodying myinvention, and will then point out' the novel features thereof inclaims.

1n the accompanyin drawingsvFigure 1 is a view s owing in top plan oneform of'exercising apparatus embodyin niyinventicn; Y f

igure 2 is a vertical longitudinal sectional view of the apparatus shownin Figure 1;

lFigures 3 and 4 are vertical sectional views taken on the lines 3-3 and4 4, respectively, of Figure 2.

Figure 5- is a section through a portion of one of the rails showing themanner of mounting the seat base thereon, the part of the seat thereinshown being also in section.

Referrin specically to the drawin in which simi ar reference charactersre er to similar parts, my invention in its present embodiment comprisesa base frame of sub stantially rectangular outline and includin spacedparallel rails or beams 15 connecte adjacent their ends by tranverserails 16. A tl-shaped yoke or frame 17 is secured in upstanding positionupon the rails 15 by Vmeans of brackets 18, and the'platform 19 isarranged yin inclined position upon the rails 15, with triangularlblocks 2() arranged between the platform and the yoke 17 for rigidlysupporting the platform in inclined position. This `platform includes astrip 21 secured to the lower edge thereof, which is designed to preventdownward displacement of the feet fromthe platform, as

will be understood, and the platform is formed at its Aupper edge with arecess 22 for a purpose which will be hereinafter described. Foot straps23 are mounted on the platform in the manner shown and are adjustable toaccommodate feet 'of dinderent s1zes. l

An, exercising device is shown as constitutingv a part of thisapparatus, and this device .is'of the conventional Wthitley form ofexerciser. This device includes an elasltic cable 24 trained about apulley 25 adjustably connected to one of the transverse rails 16 bymeans of a chain 26 and a hook 27. The cable is also trained around apair of pulleys 28 mounted in a bracket 29 secured to the other,transverse rail 16. From these pulleys the cable extends upwardly andaround a pair of pulleys 30 mounted on -a bracket'31 pivotally supportedupon the upper end of the yoke 17 byrneans of a hook 32. The free endsof the cable which l extend rearwardly from the pulleys 3G are providedwith hand grips 33, lt will be noted that the recess 22v of the platform19 allows the extension of the cable upwardly through the the footstraps 23.

A seat 34 is supported on a tubular pedestal 35 secured toa base 36which is movable longitudinally on the rails 15, and for vthis purposethe base is provided with rollers 37 (Figures l and 5) journaled in ears33 secured within recesses 39 of the base, withfthe rollers havingcontact with the upper edge of the rails 15. These rollers receive thevertical load of the basey and seat, while rollers 40 are arranged totake care of the lateral thrust of the base, and these rollers engagethe confronting sides of the rails 15 and are journaled in suitablebrackets 41 secured to and depending from the underside of the base.These brackets l1 are provided with lips or flanges 42 which' movewithin grooves cl3 formed in the confronting sides of the rails 15, andby means of these danges engaging within soy platform and between lll)the grooves the base is secured. against upward displacement, 'while atthe same time the longitudinal movement of the base on the rails isunrestricted., lt is to be noted that the flanges 42 are detachablysecured to the brackets 41 to permit the application or removal of thebase to or from the rails. For the purpose of locking the base and seatagainst longitudinal movement on the rails, l have provided a latch bolt44: (Figures 1 and il which is movable to engage or disengage any oneoli several recesses or openings 4-5 (Figure 2) formed at spacedintervals on one of the rails 15. r-l`he bolt is slidably supported uponthe corresponding bracket Ll1 and can be manually moved to projected orretracted position so as to be inserted into or withdrawn from any oneot the openings 415,

As shown in .Figures 1 and 2, that end of the rame'opposite to the end,upon which the platform 19 is mounted is provided with a platform 4Gpivotally mounted upon pintles 47 so as to alloyv the platform to occupyan inclined position similar to the platform 23. The platform 46normally occupies the horizontal position shown in Figurey Q, suchposition being defined by 'stop pins 48 projecting from tbe inner sidesof the rails 15. The platform also carries foot straps 49for securingthe feet to tbe platform, as Will be understood. lVhen-employing thisplatform exercising devices consisting of two coil springs 50 areconnected to4 eyes 51 Secured within the rails 15, and these coilsprings are provided with hand grips 52.

ln practice, the seat Se of the exercising apparatus is occupied, asillustrated in dash lines in Figure 2, With the feet oi the operatorresting on the platform 19 and engaging Within the straps 23. By leaningfor- Ward. the operator engages the hand grips 33 so that the elasticcable 2st can. be extended in edecting an exercise of the muscles of thearms, and simultaneously with this operation the operator can, through amanipulationoi the legs, cause the forward or rearward sliding of theseat on the rails in a manner similar to rowing, thereby exercising thearms, legs and back muscles. By virtue of the platform 46 the operatorcan reverse his position so that his feet are engaged Within the straps49, and by reaching rearwardly to engage the lhand grips 33 other formsof arm and leg exercise can be effected, as will be understood. lf it isdesired to eliminate the body movement of the operator on the apparatus,the seat can be locked against movement by an actuation 'of the bolt 44,as has been described. ln the reverse position of the operator on theseat nerven@ 3l he can also manipulate the spring exercisers 50 inperformmg other forms of exer- Although l have herein shown anddcscribed only `one form o exercising apparatus embodying my invention,it is to be understood that various changes and modiications may be madeherein Without departing from the spirit of, the invention and thespirit and scope of the appended claims.

Having thus described my invention, l claim:
